On more technical level, Maiolino introduces the transmission
spectroscopy as a main exoplanet characterization tool – in
the real world this is a commonly used technique that brought
up the first direct detections of exoatmospheres
[1]}, [2]}.
This method can be traced further back to the Russian scientist
Mikhail Lomonosov (1711-1765) who discovered the atmosphere of
Venus during a transit of that planet across the Sun in 1761.
[3]} summarizes the present-day status of
the transmission spectroscopy.
